Cannot modify header information

See lots of these PHP Warnings in the error_log:

PHP Warning: Cannot modify header information - headers already sent in /home/eltownhall/public_html/wp-includes/pluggable.php on line xxxx

where xxxx ranges from 1137 to 1161

I added a custom error handler to pluggable.php to display a stack trace. I found that limit_login_clear_auth_cookie() is calling wp_clear_auth_cookie() in pluggable.php.

Here is the stack trace:
1 /home/eltownhall/public_html/wp-includes/pluggable.php(1143): setcookie()
2 /home/eltownhall/public_html/wp-content/plugins/limit-login-attempts/limit-login-attempts.php(340): wp_clear_auth_cookie()
3 /home/eltownhall/public_html/wp-content/plugins/limit-login-attempts/limit-login-attempts.php(251): limit_login_clear_auth_cookie()
4 /home/eltownhall/public_html/wp-content/plugins/limit-login-attempts/limit-login-attempts.php(105): limit_login_handle_cookies()
5 /home/eltownhall/public_html/wp-includes/class-wp-hook.php(324): limit_login_setup()
6 /home/eltownhall/public_html/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters()
